WASHINGTON - Storage tanks and a tunnel that could hold millions of gallons of stormwater are being proposed to provide flood relief to two Washington neighborhoods.
District officials unveiled the plan Thursday for the Bloomingdale and LeDroit Park neighborhoods of Northwest Washington. The two communities were hard hit by flash flooding last summer.
The plan calls for converting the former McMillan sand filtration site into two storage tanks holding 3 million gallons each. And six-block tunnel under First Street would hold 6 million gallons. The McMillian phase is expected to be completed by 2014 and the tunnel by 2016.
Sewer authority officials say the plan would cost $40 million more than previous flood relief plans. And it would be finished by 2022, three years earlier than the previous plan.
